title: [Update on the epidemiology of mycetoma in Mexico. A review of 3933 cases].
abstract: Mycetoma is one of the most frequent chronic subcutaneous infections in many tropical and subtropical regions.
  
  
  OBJECTIVE
  To update the epidemiological data of mycetoma cases in Mexico.
  
  
  METHODS
  A survey in the main mycological diagnosis centers in this country was performed. Each mycologist was requested for number of diagnosed mycetoma cases, age, sex, occupation, geographic origin, type of mycetoma, and etiological agents.
  
  
  RESULTS
  Until 2012, we have registered 3,933 cases in the last 54 years. Sex distribution corresponds to 75.6% for men and 24.4% for women. In 75.72% is present in adults between 16-50 years old. The predominant work group of patients is farmers (58.41%) followed by housewives (21.79%). Most of patients come from Jalisco, Morelos, Nuevo Leon, Guerrero, Veracruz and Michoacan states. The most affected body areas are limbs (60.29%) and trunk (19.76%). Actinomycetoma has a frequency of 96.52%, and the commonest etiological agent is Nocardia brasiliensis (65.58%). Eumycetoma (3.48%) is mainly caused by Madurella grisea (28.47%) and M. mycetomatis (26.28%).
  
  
  CONCLUSIONS
  Mycetoma is an under-diagnosed pathology representing a health problem in rural regions and must be attended with more interest by the health institutions.
